LAMP surron'r.

Application filed February 12, 1920. Serial No. 358,140.

To all Q0/2077], it may concern:

Be it known that I, WILL'O. NEAHR, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Lamp Supports, of which the following is a speclfication.

The present invention relates more particularly to'means for supporting electr c lamps in their housings or bodies, and 1s especially useful in "connection with auto matic signal lamps or railwaylamps 1n Theprimary object is to'provide a simple andcompact structure that can be readily introduced into the lamp body and Will 'per mit the adjustment of the lamp, sothat the A further object 'is-to provide a structure of this type that is a complete unltg or article of manufacture, and may beso applied to the lamp body.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein q Figure 1 is, a top plan View partly in section of a lamp, showing the support in place therein. I

Figure 2 is a View in elevation with half the lamp body broken away.

Figure 3 is a View partly in elevation and partly in section of the lamp support.

F i ure it is a horizontal sectional View on the line l l of Figure 3.

Figure 5 is a perspective view of the clamping sleeve, and

Figure 6 is a detail horizontal sectional view with the top clamping element removed. x

Similar reference numerals designate corresponding parts in all the figures of the drawings.

- In the embodiment illustrated, the support comprises a base 7 preferably having opposite flat edges 9 and a flange 10 extending completely around the same. This base is provided with a central circular opening 11 and slots 12 on opposite sides of the same, the said slots being disposed longitudinally of the base and terminating short of the opening 11.

A clamping member in the form of a plate 13 is located beneath the base and extends over the opening 11. This clamping element is provided with an extension 14 having an upstanding lug 15 constituting a pivot that is slidable in one of the slots 12 and permits the lateral swinging of the element 13. The element 13 carries a centrally disposed upstanding post or sleeve 16 that extends through the opening 11 and is. -of less dlameter than the same, as will be upper end of the sleeve 16 and bears upon i the plate 19; The bore of said nut is tapered',and thus serves to contract the upper end of the sleeve when it is screwed down thereupon;

Slidably mounted in the sleeve is a standardor post 21 carrying. at its upper end a socketv member consisting of a base 22 of insulating material fixed to said post and a contractile shell 23 having ears 24 that can be contracted by a connecting screw 25. The shell preferably is made of sheet metal, and has inclined portions inset, as shown at 26, constituting threads to receive the threads of the usual plug27 carried by an incandescent lamp 28. .The base 22 is provided with a pair of binding posts 29 and 30, the binding post 29 being grounded on the shell 23, and the binding post 30 being electrically connected to a contact spring 31 within the shell 23 and adapted to engage the usual central contact projection of the lamp 28.

The above support is primarily intended to be introduced into a lamp housing or body. Such a body is shown at 32, and is provided with the usual lens 33 mounted in one side. A. suitable door 34 is provided at the opposite side. The bottom 35 is provided with a guideway 36 into which the base is adapted to slide. A bowed leaf spring 37, secured on one side of the base 7, serves to hold said base snugly in the guideway 36. With this construction, it will be evident that when the base is in position, the lamp can be easily adjusted, so that it will be properly disposed with respect to the lens 33. By loosening the nut 20, the post 21 can be raised or lowered in the sleeve 16, and said sleeve can be moved toward or from the base.
